For those that don't know, ATI has their own version of CUDA known as Brook+. It uses an extension of C.

This is the aim of OpenCL, and it's being evaluated by the Khronos Group at the moment (which includes AMD, Nvidia, and Intel among others).

I don't know what you are specifically referencing, but I believe you are misunderstanding what Intel is saying. The GPU will most likely become a part of a future many core CPU instead of being overpowered by a CPU (such as AMD Fusion). It follows a pattern that we have seen before. Initially, computers required an x87 FPU (floating point unit) coprocessor in order to do floating point math. Starting with i486 this was incorporated into the CPU because the increased real estate made it unnecessary to have the two separate. In the many core future, there will be no reason to have a discrete GPU when you can incorporate it into the CPU.

AMD actually supports a few different ways to allow programming for their GPUs. CTM is one of the low level ones (there's also CAL). But, Brook+ is the most comparable to CUDA. In fact, one of the core guys from Brook was picked up by Nvidia to work on CUDA.

That was their first attempt at GPGPU stuff. CTM- released before CUDA- was an assembly-like environment for the GPU; Very low level. Brook+ was their next edition, AMD used CTM to develop the AMD Stream SDK and Brook+ is the C-like language and compiler that uses it.

Even if CUDA were available for liscense, I doubt that AMD would be paying them for the liscensing since AMD is all about keeping platforms open and forming alliances and partnerships with those who are also reluctant to pay liscensing fees and open platforms. If push comes to shove and everyone and their mothers were using Havok's physics engine and Nvidia is losing market share due to it, I'm sure Nvidia would drop CUDA and figure out a way to get the Havok engine to work on their GPUs.

If there would be CUDA on Radeon very soon - just every Gamers PC would be able to run CUDA Applications.
Sounds good, and some Applications and Games (PhysX supporting) would use it.

In a short time it would become a standard and nVidia would be able to control it!
Not only license fees are the problem but also how fast CUDA Code runs on non NV Hardware.
AMD very likely would be the number 2 on this [with losing the money they spend into their own concept]


Havoc is Intel yes.
But the Company is working pretty much their own way, still.
Intel itself is not supporting Havoc in Hardware.
When intel brings out a Hardware solution (be it Larrabee, Chipset or CPU based) AMD got an advantage as they can establish their hardware base till then.

Getting a good share of Havoc market seems easier than PhysX market.

The Quotes are pretty much out of content.
Quoting the full article would have been better ;o)

Well I think from a business to business standpoint, AMD isn't picking up the phone to contact nVidia because nVidia will play the game of business with them. Personally, I think ATi tried to contact nVidia but was probably told that they would have to provide some of their corporate secrets regarding their 48xx and all future plans and they said no and nVidia did the same. That's the only reason that they wouldn't even agree to help the guys at the other site make the PhysX work on the ATi cards. But who knows.

I'm very glad that they aren't. Nvidia should not be the one to set the industry standard on this one, and neither should AMD or Intel. What I'm hoping happens is that DAAMIT and Nvidia keep dickering about this until OpenCL takes the lions share of the gpgpu tasks, thereby setting a standard independent of any one company which all of them have to support. That way everybody wins, especially the consumers.

AMD hasn't called Nvidia to talk about supporting CUDA, there is no doubt in my. That would be handing Nvidia the keys to the whole kingdom. CUDA would become the de facto standard in the industry and then Nvidia would be able to charge any price, set requirements for it's use, and basically behave like any monopoly. Far better that we have the current chaos as it gives the open standards a chance to gain an early foothold.
